Odour and taste sensitivity is associated with body weight and extent of misreporting of body weight

Background: Sensory factors are important determinants of appetite and food choices but little is known about the relationship between body weight and sensory capabilities. Objective: To investigate the relationship between measured body weights, misreporting of body weight and sensory capabilities. Design: In a cross-sectional sensory study, body weight was assessed by measured and self-reported body weight in healthy men (n=130) and women (n=181). Sensory capabilities were assessed as odour detection and identification, and detection for salty, sweet, sour and bitter taste. Results: Odour detection, odour identification and taste perception scores were lower in subjects with a BMI 28 kg/m2 than in subjects with a BMI or= 28 kg/m2 than in subjects with a BMI
